Description

The present approach relates to a door drive module for driving a door of a rail vehicle, a door system with a door and a door drive module and a method for operating a door system.

Rotary drives such as AC or DC motors with gears and spindles or toothed belts are used as door drives for swing sliding doors. The door is swiveled by guides, scenes or actuators. A translative movement of the door is mostly implemented either by nuts, which are driven by a rotating spindle, by toothed racks or by toothed belts. Due to their design, the systems have several components in the drive that can wear out and therefore probably have to be serviced during their life cycle.

Against this background, the object of the present approach is to create an improved door drive module for driving a door of a rail vehicle, a door system with a door and an improved door drive module and an improved method for operating a door system.

This object is achieved by a door drive module with the features of device claim 1, by a door system according to claim 10, and by a method according to claim 12.

The advantages that can be achieved with the approach presented are that a door drive module is created which, using only very few components, enables complex mobility for a door of a rail vehicle. The door can thus be moved in several levels, for example pivoting.

A door drive module for driving a door of a rail vehicle has a linear motor which has a stator with at least one coil or a magnet and a rotor with at least one magnet or a coil, the coil and the magnet being designed to produce a linear drive movement and to generate an at least partially rotary drive movement for driving the door that is coupled or can be coupled to the runner.

The door can be a pivoting sliding door. The pivoting sliding door can have at least one linearly movable and pivotable door leaf or two linearly movable and pivotable door leaves which are moved in opposite directions to open and close the door and are additionally or alternatively pivoted. The coils can be cylinder coils and, when energized, can be designed to generate a magnetic field. The door drive module is advantageously designed to drive the door in at least a first level and a second level or in several further levels. This enables the door to pivot using only one linear motor per door. The linear and, additionally or alternatively, at least partially rotary drive movement can, for example, follow a gate as a forced movement.

The stator can for example have a plurality of coils which can be arranged straight along an axis of extent of the stator and additionally or alternatively offset radially from one another in or on the stator, in particular on a helical connecting line around a stator longitudinal axis of the stator. Thus, by energizing the coils which are arranged straight along the extension axis of the stator, the linear drive movement for the rotor which has the magnet can be generated. By energizing the radially arranged coils of the stator, the at least partially rotary drive movement can be generated for the rotor that has the magnet.

The rotor can also have a plurality of magnets which can be arranged straight along an axis of extent of the rotor and additionally or alternatively offset radially from one another in or on the rotor, in particular on a helical connecting line around a longitudinal axis of the rotor of the rotor. This enables the linear drive movement and additionally or alternatively at least partially rotary drive movement of the rotor as a function of an arrangement and energization of the coils of the stator.

The stator can be shaped, for example, in the shape of a rod, a circular ring or a circular ring segment. A cylindrical shape, for example with a round cross-section, can be understood as “rod-shaped”. As a rod-shaped stator, the rotor can be guided along the stator on a lateral surface of the stator, for example. As a circular ring-shaped or circular ring segment-shaped stator, this can for example at least partially encompass the rotor in order to stabilize it when it is driven.

According to one embodiment, the rotor can be shaped like a rod, a circular ring or a circular ring segment. As a rod-shaped runner, it can be guided in a stable manner, for example, by the stator that encompasses the runner, for example, at least partially on a lateral surface of the runner. As a circular ring-shaped or circular ring segment-shaped rotor, this can for example be the Grip around the stator at least partially on the lateral surface of the stator in order to be stabilized by the latter during driving. Such a curved shape of the stator and additionally or alternatively the rotor also enables a compact arrangement of the two elements with respect to one another and thus a saving in installation space.

The coil can be accommodated in the stator or rotor and, additionally or alternatively, the magnet can be accommodated in the rotor or stator. This creates a protected possibility to accommodate the stator and additionally or alternatively the rotor. When the door opening module is in an operationally ready state, the magnet and the coil can be arranged in mutually facing sides of the stator and rotor.

According to one embodiment, at least one rotor section of the rotor can be arranged within the stator or a stator section of the stator can be arranged within the rotor. For example, at least one rotor section of a rod-shaped rotor can be arranged within a circular ring-shaped or circular ring segment-shaped stator, or a stator section of a rod-shaped stator can be arranged within a circular ring-shaped or circular ring segment-shaped rotor. In this way, guided or stabilized relative movements of the rotor and stator can be made possible. This also creates a compact arrangement of rotor and stator with respect to one another.

It is also advantageous if the stator receives at least the rotor section of the rotor circumferentially or the rotor at least receives the stator section of the stator circumferentially. In this case, the stator can be shaped, for example, in the shape of a circular ring and can accommodate a rotor section of a rod-shaped rotor circumferentially. Alternatively, the rotor can be designed in the shape of a circular ring and can accommodate a stator section of a rod-shaped stator circumferentially. In this way, stably guided or stabilized relative movements of the rotor and stator can be made possible.

It is also advantageous if, according to one embodiment, the door drive module has a guide device for guiding the door in or on the guide device and additionally or alternatively an actuator for guiding the door when the door is driven. Such a guide device can serve as a door support and guide system without the need for a further actuator. The actuator can enable electrically driven guiding of the door.

A door system has a door and a door drive module which is formed in one of the variants described above. Such a door system implements a functional system for opening and closing a door, with only very few components advantageously being used. An additional rotary drive such as a rotary motor, for example, is not necessary. With such a door system, component costs, maintenance costs, installation space and weight can advantageously be saved. The door can be coupled to the runner, in particular radially to the runner. In this way, a drive force generated by the linear motor can be ideally and evenly transmitted from the runner to the door.

A method for operating the door system has a step of energizing. In the energizing step, the coil is energized in order to move the door. In the energizing step, the coil can be energized in order to move at least one door leaf of the door linearly and additionally or alternatively at least partially in a rotary manner, for example pivoting.

This method can be implemented, for example, in software or hardware or in a mixed form of software and hardware, for example in a control device.
